    I don't know where you have got that impression, but I have always booted Mac minis (for example both 1.42GHz and 1.5GHz minis) from USB with the method presented here (you can usually skip the formatting of the USB device, if you have a FAT compatible stick):

    I tried USB booting (from that exact guide) a couple of times, and I can get to the OF boot and it takes the launch command, and I get the "Loading ELF" message, and then the next line goes to "D0-QUIESCE Finished" and just sits there forever (I don't get any lines between these two messages, in the screenshots in the guide it looks like I should see CPU info etc between the two lines?).

    CPU info is only shown on certain machines/versions, but if it's missing, it doesn't mean anything. When you do get into "DO-QUIESCE Finished" it means the boot.img has been successfully loaded from the USB device, and it should start loading the ISO image and switch the display mode to MorphOS screenmodes, so something doesn't go right with that phase. We now know that you have a working USB device, and I think that even wrong boot.img wouldn't get that far so that is probably correct too. The common mistake has been that user has given wrong name to the ISO image option (even when they have said they had it right), so double check that if you have a morphos.iso file on the USB device, boot it with "bi umsd0:morphos.iso", but if you have for example morphos-3.9.iso then with "bi umsd0:morphos-3.9.iso" and so on :)

    If that doesn't help, maybe the issue could be with the display. When you have been looking the "DO-QUIESCE" line some time and you press the Enter key, do you soon hear a boot jingle? Or if you swap for example from DVI cable to VGA cable, does it help?


    I then was googling around for USB boot options and on a forum I read the line "The mini doesn't support USB boot" - when I'm home I can source that reference :)

    In my experience you can't see and boot a bootable USB device from the Alt menu on Mac mini, but that doesn't stop it being bootable from the OF with the correct commands. And as you already have been able to load the boot.img file from OF, nothing should stop it technically I think.
